Craniopharyngioma on Gross Examination of Brain

This cystic and solid suprasellar mass, seen on this brain cut in the coronal plane, represents the classic gross appearance of a craniopharyngioma with typical focal yellow calcifications. The solid parts on gross examination correlate with enhancing regions on MRI while the cystic regions characteristically contain “machine oil”-like fluid, which is not appreciated in this brain that has been partially fixed in formalin preservative.
